A) \[7.56\times {{10}^{5}}J\,mo{{l}^{-1}}\]
B) \[9.84\times {{10}^{5}}J\,mo{{l}^{-1}}\]
C) \[8.51\times {{10}^{5}}J\,mo{{l}^{-1}}\]
D) \[6.56\times {{10}^{5}}J\,mo{{l}^{-1}}\]
Correct Answer: B
Solution :
\[{{E}_{2}}=\frac{-1.312\times {{10}^{6}}\times {{(1)}^{2}}}{{{(2)}^{2}}}=-3.28\times {{10}^{5}}J\,mo{{l}^{-1}}\,;\] \[{{E}_{1}}=-1.312\times {{10}^{6}}J\,mo{{l}^{-1}}\] \[\Delta E={{E}_{2}}-{{E}_{1}}=(-3.28\times {{10}^{5}}+1.312\times {{10}^{6}})\]\[J\,mo{{l}^{-1}}=9.84\times {{10}^{5}}J\,mo{{l}^{-1}}\]
